Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of leather production and processing, in particular to a preheating box for a leather embossing production line. Background Art
[0002] Patterns are generally printed on the surface of decorative leather, and the patterns are pressed by an embossing roller. The leather needs to be preheated before embossing the patterns. At present, the leather is preheated by a preheating box. The leather passes through the preheating box, and the heating pipes inside generate heat to preheat the leather. During the conveying process of the leather, the heat will be driven to move towards the outlet of the preheating box, resulting in uneven heat inside the preheating box, affecting the heating of the leather surface, and causing the leather to fail to reach the preheating temperature. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a preheating box for a leather embossing production line aiming at the above-mentioned deficiencies of the prior art.
[0004] To solve the above technical problem, the technical solution adopted by the utility model is:
[0005] A preheating box for a leather embossing production line, including a preheating box body. A leather inlet and a leather outlet are respectively arranged on the feeding side and the discharging side of the preheating box body. A cloth guiding roller is arranged inside the preheating box body, and electric heating pipes are installed at the bottom inside the preheating box body. A first hot air box and a second hot air box are respectively installed on the feeding side and the discharging side of the preheating box body. An air outlet is processed on the feeding side of the preheating box body and communicated with the first hot air box, and an air inlet is processed on the discharging side of the preheating box body and communicated with the second hot air box. The bottoms of the first hot air box and the second hot air box are communicated through a heat transfer pipeline, and a conveying fan is installed on the conveying pipeline.
[0006] Further, the leather inlet and the leather outlet are flared mouths, and the small mouths of the flared mouths face the inside of the preheating box body.
[0007] Further, the cloth guiding rollers are distributed at intervals up and down inside the preheating box body.
[0008] Further, a baffle is installed at the bottom inside the preheating box body, and heat dissipation holes are evenly distributed on the surface of the baffle.
[0009] Further, the conveying fan adopts a centrifugal fan.
[0010] Compared with the prior art, the preheating box for a leather embossing production line of the utility model transports the heat concentrated on the discharging side of the preheating box body to the discharging side, forming heat convection, making the heat inside the preheating box body uniform, and enabling the leather to reach the preheating temperature. Description of the Drawings
[0011] Figure 1 It is a schematic structural diagram of the utility model;
[0012] Among them, 1. Preheating box body, 2. Leather inlet, 3. Leather outlet, 4. Cloth guiding roller, 5. Electric heating tube, 6. Baffle plate, 7. Oven, 8. First hot air box, 9. Air outlet, 10. Air inlet, 11. Conveyor fan. Specific implementation mode
[0013] The technical solutions in the embodiments of the present utility model will be clearly and completely described below.
[0014] As Figure 1 shown, a preheating box for a leather embossing production line includes a preheating box body 1 made of heat-insulating material. A leather inlet 2 and a leather outlet 3 are respectively arranged on the feeding side and the discharging side of the preheating box body 1. A cloth guiding roller 4 is arranged in the preheating box body 1, and the cloth guiding rollers 4 are distributed at intervals up and down in the preheating box body 1. Electric heating tubes 5 and baffle plates 6 are installed at the bottom inside the preheating box body 1, and heat dissipation holes are evenly distributed on the surfaces of the baffle plates 6. During preheating, the leather passes through the leather inlet 2, winds around the cloth guiding roller 4, and then passes through the leather outlet 3. Then, after the electric heating tubes are powered on, they heat up to preheat the leather.
[0015] A first hot air box 7 and a second hot air box 8 are respectively installed on the feeding side and the discharging side of the preheating box body 1. An air outlet 9 is processed on the feeding side of the preheating box body 1 and communicated with the first hot air box 7, and an air inlet 10 is processed on the discharging side of the preheating box body 1 and communicated with the second hot air box 8. The bottoms of the first hot air box 7 and the second hot air box 8 are communicated through a heat transfer pipeline, and a conveyor fan 11 is installed on the conveying pipeline.
[0016] In this embodiment, the conveyor fan 11 adopts a centrifugal fan. The heat transfer pipeline is respectively communicated with the first hot air box 7 and the second hot air box 8 through elbow joints, and the heat transfer pipeline is connected to the air inlet pipeline and the air outlet pipeline of the centrifugal fan through flanges. During preheating, the hot air on the discharging side of the preheating box body 1 is introduced into the feeding side to realize heat convection inside the preheating box body 1 and make the heat inside the preheating box body 1 uniform.
[0017] In this embodiment, the leather inlet 2 and the leather outlet 3 are flared mouths, and the small mouths of the flared mouths face the inside of the preheating box body 1, so as to reduce heat loss.
[0018] The present utility model is not limited to the described embodiments. Those skilled in the art can still make some modifications or changes without departing from the spirit of the present utility model, that is, within the scope of disclosure. Therefore, the scope of the protection of the rights of the present utility model is subject to the scope defined by the claims.
